Munich during Oktoberfest
I can't give a review of the actual city of Munich because I was there during such a special time. I loved Oktoberfest though. It was like disneyland for adults. Everyone is so nice, so friendly and SO SO FUN. You do not have to be in line at 7am to get a table so dont listen when people tell you that. You can show up whenever and squeeze in and make new friends. I was with a group of 5 and we never had a problem. If you are a group of 20 waiting and getting a table may be worth it though.
Insider Tip:Get a German sim-card for 10 Euro and put it into your phone. You will get unlimited data for a month which is totally worth it. Google maps knows all the public transport in the city so it is so easy to find your way around if you have internet. Totally worth it. Especially if you are there during Oktoberfest, aka too drunk to remember anything let alone read a real map.
